You spoilsport. :) While we're at it: it may be useful, at times, to sort on more than one series. Or at least, I had to do this from time to time. At present, you can do this by constructing an artificial key series. Example with the Mroz dataset: <hansl> open mroz87 series key = WE * 100 + WA dataset sortby key print WE WA --byobs --range=1:32 </hansl> However, this is neither particularly efficient nor elegant. Would you think it worthwhile to add a list as a possible argument to "dataset sortby"? Eg <pseudo-hansl> list SORT = WE WA dataset sortby SORT </pseudo-hansl>
